This invention relates to tubes or cores on which yarn to be processed, is wound and supported while dyes or other yarn-treating agents are forced through the yarn. a

The primary object of the invention is to provide a tube or core of this character, wherein the yarn or material wrapped thereon will be uni formly exposed to the treatment of the dye or material passing through the tube, to insure an even treatment of theyarn supported on the tube or core.

' An important object of the invention is to'provide a tube having grooves and perforations arranged s'othatthe' perforations intersect one or more grooves to the end thata greater quantity of yarn- -treating fluid may contact the yarn under treatment, which: is important when the viscosity of the yarn-treating fluid; is'substantially With the foregoing and other objects in view which'will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of-parts hereinafter more fullydes'cribed -and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departingfrom the spirit 'of the invention as claimed. y Referring to the'drawing;

Figure 1 is an elevational view illustrating, a tube constructed inaccordance with the, invention, the tube having; parallel l grooves; extending longitudinally thereof, .the grooves being disposed in the periphery of the tube, and elongated perforations .formed to intersect the grooves, the perforations; being elongated transversely of the tube.

Figure!) is a fragmental elevational view of a further modified forn of thedevelopment of the tube.

Figure 10 is an elevational view of a still further development of the invention.

Referring to the drawing in detail, the body portion or tube is indicated by the reference character 5, and as shown, is provided with longitudinal grooves 5 equally spaced, the ends of the grooves terminating 'in' spaced relation withthe endsof the tube.

7 Perforations 7 are-formed in the tube, theperforations b i 1 transversely elongated and arranged so that they intersectthe grooves, the elongated perforations extending through the wall of the tube, establishing communication betweenthe interiorofthe tube and the grooves. These perforations are arranged in staggered relation with respect to each other; as clearly shown by Fig. 1 of the drawing.

As .shown by Fig. 3 of the drawing, the outer surface of theltubeisprovided with'longitudinal spaced grooves 8 providing" passageways for the fluid forced through the tube. Circular openings 9 extendthroughthe" wall'ofthetube and are disposed within the grooves 8.. Openings'l (E which are also eirculari'in formation, are disposed in the ribsformed by' 'thejfgrooves between the grooves, the latter spemngs. also, extending through the wallof'tlleitubel :As shown by 4of the drawing, annular grooves H are forme in the periphery'pfthe 7 tube, and are arra n ged in'spaced relation with respect toea ch other; longitudinally of the tube. The axes-of the gannular grooves are me line parallel with the longitudinal axis or the tubular member; l? erforations or openings 12 areformed in the wall of the tube and extend through the wall of the tube, certain of the openings being disposed between the grooves so that the openings l2 establish communicaton between adjacent grooves, as well as between the grooves and the interior of the tube.

a In the modified form of the invention as illustrated by Fig. of the drawing, the body portion or tube is provided with annular grooves l3 which are arranged in spaced relation with respect to each other. Elongated perforations id are formed in the body portion or tube and are so constructed that they establish communication between adjacent grooves, the ends of the elongated perforations l4 extending appreciable distances into the grooves I3.

As shown by Fig. 6 of the drawing, the annular grooves l5 are arranged circumferentially of the body portion or tube, and elongated perforations it are provided and disposed at acute angles with respect to a plane: disposed at right angles to the longitudinal axis of the body portion or tube, the elongated perforations 16 being of lengths to extend across the annular grooves, the ends of the elongated perforations extending appreciable distances into the ribs or spaces formed between the annular grooves l5, so that the yarn contacting with the annular grooves I5, may be treated by the fluid forced into the tube.

The grooves 11 as shown by Fig. 7 of the drawing, are disposed longitudinally of the body portion or tube and are arranged in parallel spaced relation with respect to each other. Elongated perforations iii are formed in the body portion or tube and are disposed in circular lines around the body portion or tube. These elongated perforations are disposed at acute angles with respect to the side walls of the grooves l1, and are of lengths to extend. across the grooves, intersecting two or more grooves.

In the form of the invention as shown by Fig. 8 of the drawing, the grooves I9 are formed in the outer surface of the body portion or tube, and are equally spaced and spirally arranged. Elongated perforations 20 are formed in the body portion or tube, and these perforations establish communication between the grooves and interior of the tube. These perforations also extend appreciable distances into the ribs or surface formed between the grooves, as clearly shown by the drawing.

It will of course be understood that the body portion or tube may be constructed of any suitable material, and the size of the grooves and shapes of the apertures may be varied to meet Various requirements.

It will also be noted that because of the elongated openings, a more even flow of the treating fluid will be assured, particularly when the fluids are thicker or heavier, as to viscosity.

It might be further stated that While I have shown and described the body portion as tubular in formation, it is to be understood that the body portion maybe of any desired hollow construction, such as a cone or the like, without departing from the spirit of the invention.

The width and the depth of the grooves and diameter of the perforations may be varied within the scope of the invention.

As shown by Fig. 9 of the drawing, the tubular 7 body portion is provided with grooves 2 I extending longitudinally of the body portion, the grooves being regularly spaced apart.

Annular grooves 2 2 are also formed inthe surface of the body portion, and these grooves are arranged in vertical spaced relation with respect to each other, the grooves 22 intersecting the grooves 28 providing regular passageways throughout the surface of the body portion.

Substantially large openings 23 are formed in the body portion and are arranged in predetermined spaced relation with respect toeach other, the openings or perforations 23 establishing communication between the interior of the tube and the grooves intersected by the openings 23. These openings 23 are of diameters greater than the width of the grooves 2| and 22, so that the openings 23 establish communication between one or more grooves, depending on the locations of the openings.

0 In Fig. 10 the body portion which is in the form of a tube, as indicated by the reference character 24, is. provided. with grooves 25 extendmg longitudinally of the body portion in prede-. termined spaced relation with respect to each other.

Grooves 26 are formed in the outer surface of the body portion and are extended at right angles with respect to the grooves 25, the grooves 26 intersecting the grooves 25 Openings 2? are also formed in the body portion and establish communication between the inter or of the body portion and grooves 26, the openings 2'1 being shown as disposed between the grooves 25. I

This construction permits of an even flow ofthe dyeing fluid regardless .of the viscosity of the dyeing fluid, to insure an even dyeing of the thread wound on the tubular body portion. It might be further stated that the tube forming thesubject matter of this invention providesa practical core for supporting filtering material and the device used as a filtering member in oilor other pipe lines.
